An alternative it to add a SYSCTL_xxx_ALL_CHILDREN which would return all
the data for the next level down in a described format.
struct {
int mib_tag;
int mib_flags; /* length, padding, type, RW/RO,
HAS_CHILDREN */
union {
int32_t v_int32;
int64_t v_int64;
char v_string[1];
}
}
or something like that.
